You have everthing to make the car run. Timing, spark , and fuel. If you have all so the above I have I feeling you may have fouled out the plugs from trying to start the car. You may have rerplaced the defected part a few parts ago but never realized it. (I've done this before) Sometimes the answer is so simple we look right over it.
Hope this helps Backyardmechanic :(

Suggested Repair

Inspect and replace spark plugs that may be fouled from repeated start attempts, and recheck whether an earlier parts replacement already fixed the original fault.

Conversation Summary

A 1991 V6, described as the same as a 4Runner, shut down with no power after 25 miles and now only cranks. The owner replaced the battery, ground cable, fuel pump, filter, circuit opening relay, ECU, and airflow meter, and reports spark, correct timing, good compression, and a pump that runs when the air valve is opened by hand. The expert says the basics for running are present and suggests fouled plugs from repeated start attempts, or that an earlier repair already fixed the fault.
